To all whom 2'25 may concern:

Be it known that I, ALBERT HE'NNING Ernnrnr BECKMAN, a subject of theKing of Sweden, and a resident of Vasagatan 5, in the city of Stockholm,Sweden, have invented an Improved skee-Stopper, (for which I have filedapplication for Letters Patent of Sweden, -March 24, 1919, No. 1,366,and May 14, 1921, No. 1,997,) of which the following is a specification.

The invention relates to skee-stoppers, which are intended to preventbackward sliding of the skees.

My improved skee-stopper consists of a pivoted rearwardly directed armwhich slides on the ground (snow or ice) when the skee is moved forwardand is adapted to enter the ground when the skee begins to slidebackward, means being rovided to limit the up and down swingingmovements of said arm and to easily remove it when its use is not wantedand quickly replace it whenever desired and'to prevent undesired removalwhen-in use.

In the drawing- Figure 1 is a side elevation of the middle portion of askee with the stopper mounted thereon.

Fig. 2 is a plan view of the stopper and the'bearing for its pivot.

Fig. 3 is a side view of the moved from the bearing.

Figs. 4 and 5 are plan view and side view of the bearing.

Figs. 6, 7 and 8 show a modification.

Fig. 9 is a perspective view of theskee showing the stopper mountedthereon.

Figs. 10 and 11 are plan view and side view of a modification.

Fig. 12 is side view of a detail of same.

Figs. 13 and 14 are views (partly sectional) of another modification.

Referring to Figs. 1-5 and 9 the stopper consists of an arm 1 extendingrearward at the outer side edge of the skee and bent to a right angle atthe fore-end so as to form a pivot 2 which is passed through lugs 3, 4of a bearing piece 5 fixed to the upper side of the skee by screws orotherwise so that the arm 1 is adapted to swing up and down. WVhen theskee is moved forward the arm will slide'on the snow or ice and nothinder the movement but if the skee tends to slide backward the pointedor flattened sharp rear end of the arm will at once grasp or penetratethe ice or snow and stopper rewill be locked in this grasping positionso as to stop or prevent further backward movement "of the sheer F orthis purpose a collar 6 isfixed'on the pivot'2 adjacent to the outer lug3, and this collar has a tooth 'Twhich engages an outwardly bent tongue,

6 on the lug. The free end of the tongue is further bent downon theoutside of the collar as shown at 9 (Fig.2) so as to prevent undesiredwithdrawal of the pivot from the lugs. dlametrically opposite the tooth7 allows such withdrawal when the arm is swung upward so far that thisnot-ch coincides with the tongue.

Figs. 6-8 show that the tooth 7 and notch 10 may be on the lug 3 and thetongue 89 on thecollar 6, if preferred. When assembling the parts thepivot is A notch 10 on the collar V inserted in the lugs as, far as thetongue allows and then rotated until; the notch reaches the tongue andallows'the full insertlon of the pivot. Then the arm 1 should be allowedto, swing downso as to bring the notch from the I with the tongue. V

' lnthe modification shown in Figs.- 1012 position of coincidence thecollar 7 is=dispensed withand suhsti- 'tuted by a lockingplate 1?pivoted at 16 to one of the lugs for instance the lugs-1,

and adapted to'engage a transverse slot 19 on'the pivot 2. p

*Th'isslot 19 reaches thev center of the pivot-2 and hasa straightbottom which conurs with a diameter of thepivot;

The plate 17 is preferably pivoted eccentrically with regardto itseenter' of gravity so that it tend'sto turn counter-clockwise in Fig.12. The turning is limited by "a tongue 18 provided at the upperleftcorner of the plate and bent over the edge of the lug 1. or by a tail 20at the lower left cor ner of the plate which tail rests on the left sideof the pivot 2.

The pivot of the plate 17 is situated above the pivot 2 of the arm 1,and the lower edge of the plate adjacent to the tail 10 is an gular orpointed as shown, id 682." has two edges 21, 22 whi h form an angle ofabout 90 with each other.

When the tail 1O rests on the left side of the pivot '2, the point 23where the two edges meet will be atthe counter of the pivot within theslot. When the arm 1 is in its lower or working position (with its pointforced down in the snow) the edge 21 coacts with at left half of thebottom er the slot and prevents further downward turning of the arm 1;;When the arm is raised to the position shownby dotted lines in Fig. 11,the other edge 22 of the plate'17 engages the otherhalf ofthe bottom ofthe slot and prevents further upward movement of the arm; Forwithdrawing the pivot 2 from the lugs, or'for', inserting it in the samethefarm 1 should be turned upward about to.,horizontal position andwhile the armqis in suclrposition the plate 17 shouldbe turned clockwiseby lifting the tongue 18 (hymeansyof a finger) so as to disengage theplate from the slot. Then the pivot 2 can beremoved or inserted.

The forms now described" are the preferred ones; Idonot wish, however,to be limited to these forms as others based on the same principle maybe 'used.
